Abstract
A parabolic reflector device (also referred to herein as a parabolic lens device) is disclosed which includes a plurality of parabolic lens members and a mirror member which couple together and collectively provide a light-transmissive structure for multiplexing or demultiplexing of an optical signal. The parabolic reflector device can be implemented within optical subassembly modules to support operations of transmitter optical subassemblies (TOSAs) and/or receiver optical subassemblies (ROSAs).
